Abstract: 1,058,517. Controlling furnaces. COMBUSTION ENGINEERING Inc. June 24, 1965 [July 13, 1964], No. 26900/65. Heading F4T. The presence of a flame in an upright furnace is indicated by the position of a beam 54 pivoted at 55 and having its ends connected to two diaphragms 48, 50. The diaphragm 48 is responsive to the pressure difference between two points 36, 38 spaced vertically a distance d 1  in the furnace and the other diaphragm 50 is responsive to the pressure difference between the point 38 and a third point 40 spaced vertically a distance d 2  in the furnace; and the ratio of the lengths a 1 , a 2  of the two arms of the pivoted beam is inversely proportional to the distances d 1 , d 2  between the three points 36, 38, 40. The beam is provided with an indicator. In a modification, Fig. 3, not shown, the beam and the diaphragm are replaced by two cylinders (74, 75) having two pistons (71, 72) connected to a common piston-rod (73) the position of which indicates the presence of a flame. The pressures at three points in the furnace are conveyed by pipes (41, 43, 45, 47) to the spaces on each side of the pistons and the ratio of the areas of the pistons is inversely proportional to the ratio of the distances between the three points in the furnace. In a further modification, Fig. 4 (not shown), the movement of the two diaphragms strains two gauges (S, R) forming arms of a Wheatstone bridge and causes changes in their resistances. The changes are detected by a voltage meter (78) across the bridge output.

Abstract: 789,981. Seaming. PAPER SACKS, Ltd. Sept. 7, 1955 [Sept. 30, 1954], No. 28185/54. Class 42 (1). In the manufacture of bag tubes from a thermoplastic-coated paper web, a blow-pipe flame is directed upon a continuously travelling coated margin of a tube-forming web, or a selected ply of a multiply bag tube, the margin is folded in overlapping relation with the opposite margin of the web and pressure is applied to the overlapped margins to secure them together while the thermoplastic coating is a fused condition. As shown, Fig. 1, the overlapping edges la, 1b of a polythene-coated paper web in a bag-tube-making machine travel below and above the flame 16 from a burner 7 and are then sealed by a spring- pressed roller 14 and a fixed or spring-pressed roller 15. An auxiliary burner 12 may direct flames against the two edges 1a, 1b to pre-heat the surfaces. Pilot jets 11, 11a are provided, burners 7, 12 being supplied with a mixture of air or oxygen and acetylene or other inflammable gas through a control valve operated by a solenoid 8. The solenoid is operated by the machine drive so that the flames are lit when the web starts moving or reaches operational speed and are extinguished when the web stops or slows down below operational speed. The nozzle of burner 7 is shrouded at 13 to prevent sealing heat reaching the web before it arrives at the sealing nip. The supporting arm 14a of roller 14 is carried by a base-plate 4 fixed to the machine. Plate 4 supports a table 5 which is transversely adjustable by a screw 10 and carries the burners and solenoid 8. When seaming paper coated on the inside with polythene, a simple lap joint may be used to seal a coated surface to a non-coated surface; alternatively, the margin 1a may be pasted back at 1c, Fig. 4, to enable two coated surfaces to be sealed together. When seaming a multiply tube, Fig. 6, the innermost ply of which is coated with thermoplastic, the innermost ply is seamed by other flame heating and the seams 17 of the other plies are sealed by pasting; where a thermoplastic coating is applied to plies other than the innermost one, all such plies may be seamed by flame heating, the burners for the various plies being laterally and longitudinally staggered.

In a pulse-echo type of fault detector for electric cables signals due to irregularities in the cable 3 are supplied via a differential coupling device 5 to a stroke device 7 in which pulses from a generator 8 controlled by an oscillator 9 sample the echo signals and supply such samples to the vertical deflection plates of an oscilloscope 14 via amplifier 13. The frequency fr (oscillator 1 and pulse generators 2) of the pulses supplied to the cable and the frequency fe of the oscillator 9 and pulse generator 8 are so chosen with respect to the frequency of the highest spectral component f max in the output of device 7 that f max fr-fe/fr < fe where fr-fe/fr is the ratio in which the frequency of spectral component in the output of device 7 are reduced with respect to those of the echo signal. The horizontal deflection of oscilloscope 14 is produced by a saw tooth wave of frequency fr-fe in generator 12 controlled by a mixer 11 in which the difference signal is produced from the output of oscillators 1 and 9. The cable 3 and the other end of device 5 are terminated in impedances 4, 6 equal to the characteristic impedance of the cable and a measure of the total echo energy may be obtained from an integrating device 10.
